As many of you know, several years ago I lost my left wrist bones to a rare disease called Kienbock's. My surgeon moved 3 upper bones down to become my new wrist. Conditioning polymer was good therapy to strengthen my hand after the surgeries. But, there are still times when I need to wear a brace or just rest my hand. When I saw this kneading machine invented by a polymer clay artist, I thought it was worth a try for me. I ordered it, used it and love it. It has been worth every penny for me. I don't get anything for endorsing it, I just thought I would pass it along. It is basically a press that gives a ton of pressure; extremely well made.
